What are the similarities between mechanical weathering and chemical weathering?
Both mechanical weathering (physically breaking rock into smaller pieces) and chemical weathering (chemically changing and even dissolving rock) result in rock layers being broken down. Water can be involved in both - freezing and then thawing lead to mechanical breaking by cracking rock, dissolving can lead to leaching chemical components of the rock, possibly weakening it and leading to pitting of the surface, for example. Also they both can break down some rocks faster than other rocks.
What are the similarities between biological weathering and chemical weathering?
Weathering is weathering, no matter how it occurs. Both chemical and biological weathering wear down rock. They simply go about it in different ways.
Can explain two way in which weathering may be influence by rock type?
Weathering is influenced by rock type in two key ways: mineral composition and texture. For instance, rocks rich in softer minerals, like limestone, tend to weather more easily through chemical processes, such as dissolution, compared to harder igneous rocks like granite. Additionally, the texture of the rock, including its porosity and grain size, affects the rate of physical weathering; porous rocks absorb water, leading to freeze-thaw cycles that can break them down more rapidly.
What types of rocks can become igneous rocks?
All rocks can become igneous rocks. With weathering and erosion, an igneous rock can become a sediment. Then with compaction and cementation, it can become a sedimentary rock. With heat and pressure, it will turn into a metamorphic rock. Or it can melt and turn into an igneous rock. There are many more ways rocks can change types... that is the rock cycle.
What rock changes?
Everything. There is so many ways to change rocks. Erosion by Wind and Water. Earthquakes/Plate Tectonics, Subduction leading to metamorphism and ultimately melting and becoming Igneous. Man.
What involves ways that rocks break down without changes to what?
Weathering involves ways that rocks break down without changes to their chemical state. Weathering involves mechanical forces e.g. wind and rainfall rather than chemical energy in disintegration or rocks.
What are two ways than mechanical weathering changes rock?
Tree roots can grow in cracks of rocks and break the rocks. The rocks of mountains change due to many kinds of weathering.
What involves ways that rocks break down without changes to?
Weathering involves ways that rocks break down without changes to their chemical state. Weathering involves mechanical forces e.g. wind and rainfall rather than chemical energy in disintegration or rocks.
How do animals cause mechanical weathering?
Animals cause mechanical weathering in various ways. One of the common ways is by stepping on rocks with their hooves and breaking them down.

What are the 4 ways of weathering?
The four main types of weathering are mechanical weathering, chemical weathering, biological weathering, and physical weathering. Mechanical weathering involves the physical breakdown of rocks, chemical weathering involves the decomposition of rocks through chemical processes, biological weathering involves the actions of living organisms on rocks, and physical weathering involves the breaking down of rocks by natural forces such as wind or water.
What are two ways that chemical weathering changes rocks?
Physical and Chemical
What are two ways mechanical weathering change rocks?
Two forms of mechanical weathering are frost heaving and plant root wedging. All forms of mechanical weathering result in the breakage of rock into smaller size particles.
What are the forces that break rocks?
The main forces that break rocks are weathering, which includes mechanical, chemical, and biological processes. Mechanical weathering involves physical forces like temperature changes and frost action breaking down rocks. Chemical weathering occurs when rock minerals react with water and air, leading to their breakdown. Biological weathering involves living organisms like plants and animals contributing to rock breakdown through physical and chemical processes.
What are two ways rocks are mechanically weathered?
Two forms of mechanical weathering are frost heaving and plant root wedging. All forms of mechanical weathering result in the breakage of rock into smaller size particles.
What are the five ways of mechanical weathering?
There are 5 ways Mechanical Weathering acts: 1. Freezing and Thawing 2. Release of pressure 3. Plant growth 4. Actions of Animals 5. Abrasion
Are weathering and erosion the same process?
Both chemical and mechanical weathering breakdown a rock into particles, just in diffrent ways. Mechanical weathering is the physical weathering in which a rock is broken down into particles. Chemical weathering is the weathering in which rocks are disolved, decomposed , or loosend to change the minerals in the rock.
